Definitions
- the invention relates to a process for the preparation of salts of dialkylphosphinic acids and the use of the salts of dialkylphosphinic acids prepared by this process.
- Aluminum salts of organic phosphoric acids are known as flame retardants. They can be made by various methods.
- EP-A-0 299 922 describes a process for the preparation of aluminum salts of Phosphoric and phosphonic acid esters by reacting aluminum with Phosphoric acid, phosphonic acid or an ester thereof.
- the conversion of aluminum hydroxide is carried out Alkylphosphonic diesters in the absence of water also at about 180 ° C.
- EP-A-0 699 708 describes flame-retardant polyester molding compositions, the Polyester through the addition of calcium or aluminum salts of phosphine or Diphosphinic acids are made flame-resistant.
- the aforementioned salts are by Implementation of the corresponding dialkylphosphinic acid with calcium or Obtain aluminum hydroxide.
- DE 21 00 779 A1 describes a process for the preparation of dialkylphosphinic acid alkyl esters by adding olefins having 2 to 22 carbon atoms Alkylphosphonous.
- the invention is therefore based on the object of a method for producing To provide salts of dialkylphosphinic acids, which relate to particular simple and economical way both the dialkylphosphinic acids and their Alkali salts as well as the desired end products, namely dialkylphosphinic salts of certain metals.
- the azo compounds are preferably cationic and / or non-cationic Azo compounds.
- 2,2'-Azobis (2-amidinopropane) dihydrochloride are preferred as cationic azo compounds or 2,2'-azobis (N, N'-dimethyleneisobutyramidine) dihydrochloride used.
- Preferred non-cationic azo compounds are azobis (isobutyronitrile), 4,4'Azobis (4-cyano-pentanoic acid) or 2,2'Azobis (2-methylbutyronitrile) are used.
- the metal compounds are preferably metal oxides, metal hydroxides, Oxide hydroxides, sulfates, acetates, nitrates, chlorides and / or alkoxides.
- the metal compounds are particularly preferably aluminum hydroxide or aluminum sulfates.
- the product mixture obtained after step a) is preferably used without further purification implemented the metal compounds.
- step a) that obtained after step a) is obtained Worked up product mixture and then only the dialkylphosphinic acids obtained after step a) and / or their alkali salts are reacted with the metal compounds.
- alkylphosphonous acid and / or its alkali metal salts are preferred around methylphosphonous acid or ethylphosphonous acid and / or their alkali salts.
- the reaction in step a) is preferably carried out at a temperature of 40 to 130 ° C.
- the reaction in step a) is particularly preferably carried out at a temperature of 70 to 110 ° C.
- the reaction in step b) is preferably carried out at a temperature of 20 to 150 ° C.
- the reaction in step b) is particularly preferably carried out at a temperature of 80 to 120 ° C.
- the reaction in step b) is preferably carried out in acetic acid medium.
- step b the reaction in an aqueous medium is also preferred.
- step b) takes place after setting one for the respective system Dialkylphosphinic acid / metal compound optimal pH range for salt precipitation.
- the subject of the present invention in particular also includes a method in which which one has sodium hypophosphite with ethylene in the presence of a cationic or non-cationic Azo compound as a radical starter for Reacts sodium salt of diethylphosphinic acid as the main product.
- This product is then inventively with aluminum hydroxide or a Aluminum sulfate converted to the aluminum salt of diethylphosphinic acid.
- the invention also relates to the use of the process according to the invention prepared dialkylphosphinic salts of the metals for the production of Flame retardants.
- the invention relates to the use of those produced according to the invention Dialkylphosphinic salts of metals for the manufacture of flame retardants for thermoplastic polymers such as polyethylene terephthalate, polybutylene terephthalate, Polystyrene or polyamide and for thermosets.
- the invention also relates to the use of the according to the invention Process produced dialkylphosphinic salts of the metals as additives in polymers Molding compounds.
- the total weight was 11.7 kg. This corresponds to an ethylene intake of 1.2 kg (100% of theory).
- the ethylene uptake was 1160 g (100% of theory)
- a mixture of 2.64 kg (20 mol) of a 50% aqueous solution of hypophosphorous acid and 7 kg of acetic acid was placed in a 16 L double jacket pressure reactor made of steel enamel. After the reaction mixture had been heated to 100 ° C., ethylene was introduced into the reactor through a reducing valve set to 5 bar until saturation. A solution of 56 g (1 mol%) of 4,4'-azobis (4-cyano-pentanoic acid) in 500 g was added over a period of 6 h with constant stirring at an ethylene pressure of 5 bar and a temperature of 100-105 ° C. Acetic acid metered in evenly.
- the ethylene uptake was 1160 g (100% of theory)
- the solution obtained according to a) was largely freed from the solvent acetic acid on a rotary evaporator and then mixed with 10 L of water. 4500 g (3.5 mol) of a 46% aqueous solution of Al 2 (SO 4 ) 3 .14 H 2 O were added within one hour. The solid obtained was then filtered off, washed in succession twice with 2 L each of acetic acid and 2 L of water and dried at 130 ° C. in vacuo. Yield: 2520 g (82% of theory).
